ADJUSTABLE SPRING-SEAT.

Specification of Letters Patent. Patented Oct. 28, 1919.

Application filed March 29, 1919. Serial No. 285,990.

while specially. designed for attachment to the cab of a locomotive for use by the engineer or fireman, may be employed with equally good results in many other relations Where a seat of this general character is required.

The object of the invention is to provide a springseat of simple and durable construction capable of being adjusted both vertically and laterally with respect to its support and which may be readily swung downwardly to inoperative position against said support when not in use so as to occupy very little space.- I p The invention further aims to provide an adjustable spring seat including spaced tubular members orhangers having cushloning springs arranged therein [and whlch serve to yieldablysupport a vertlcally movable rod on which is .pivotally mounted a removable seat, there being a supporting leg pivotally connected with the bottom of the seat and serving to yieldably support the forward end of said seat.

The invention further aims to provide anvauxiliary seat supporting rodor bracket adapted to be used in lieu ofthe main seat supporting rod in case the latter should become accidentally broken and from which auxiliary rod the seat may be convemently suspended when desired. 1

r A still further objectof the invention is generally to improve this class of devices so as to increase their utility, durabillty and efiiciency. Y i

The improved device comprises spaced tubular hangers '5 closed at their lower-ends and open at their upper ends, said hangers being each provided with an upstanding attaching ear 5 and oppositely disposed side attaching ears 6 through which extend bolts or similar fastening devices 7 for the purpose of securing the hangers'in position on a support indicated at '8. 1 The innerfaces of the tubular hangers 5 are provided 'withvertical slots 9 which open throu'gh the tops thereof with thelower endsof'said slots preferably spaced a short distance above the closed endsof the hangers-as best shown in Fig. l of the drawings. Arranged within the hangers 5 are main'and'auxiliary cushioning springs '10 and 10 which serve-t0 yieldably support a transverse seat carrying rod indicated at 11. The rod ll'=is preferably cylindrical in shape and is provided at its opposite ends with reduced necks 12 which fit within the slots 9 and terminatein substantially flatcircular heads 13 adapted to bear against-the cushioning springs in the adjacent hangers.

Pivotally mounted for swinging 'movement 0n the supporting rod 11 is a seat 14 to the bottom ofwhich are bolted orotherwise rigidly securedtransversecleats '15 the rear ends of which" terminate in hooks 16 adapted to embrace the'supporting rod 11 so as to permit theseat to be swung 'downwardly to inoperative position as indicated in dotted lines'in Fig. 3 of the drawings.

Secured to" the bottom of the seat-'14L-is an intermediatecleat l7 the forward end of which is provided with a depending eye 18 which receives-acorrespondingeye 19 formed on the adjacent end of a supporting leg 20. The supporting leg QO-is preferably in the form: of a threadedbolt: and surrounding the threads on said bolt is a coiled spring 21 the lower end of which is adapted to bear against the floor and form a yieldable sup;

port for the front end of the seat. The spring 21 is retained in position on the leg or bolt 20 by means of a substantially U- shaped clip 22 one end of which is provided with a slot for the reception of the bolt and is interposed between the adjacent coils or convolutions of the spring 21 and is bent into engagement therewith, while the other end of the U-shaped clip is perforated to permit the passage of said bolt and is interposed between locking Washers 23, as best shown in Fig. 5 of the drawings. If desired an auxiliary spring 24: may be arranged within the main spring 21 and threaded on the lower end of the bolt 20. By rotating the nuts on the supporting leg or bolt 20 the main spring 21 may be supported at any desired height on the leg 20.

Arranged within the tubular hangers 5 are one or more spacing members or disks 25, by removing or adding which the height of the supporting rod 11 may be varied at will. Slidably mounted on the supporting rod 11 are a plurality of tubular members or rings 26 said rings being interposed between the hangers 5 and the sides of the adjacent cleats 15 so as to center the seat on the supporting rod. It is obvious that by shifting the rings 26 longitudinally on the rod 11 the seat 1 1 may be adjusted laterally with respect to the support 8.

It will thus be seen that the supporting rod and cushioning springs 10 and 10 form a yieldable support for the rear end of the seat 1 1 while the leg 20 and spring 21 form a yieldable support for the forward end of said seat.

By swinging the supporting leg 20 laterally on its pivot 19 the seat may be folded downwardly and inwardly against the sup port 8 so as to occupy very little space when not in use.

Arranged abovethe seat 14: and detachably secured to the support 8 by screws or similar fastening devices 27, is an auxiliary seat sup-- porting rod 28 from which the seat 14L may be suspended when desired as indicated by dotted lines in Fig. 1 of the drawings. The auxiliary supporting rod 28 may also be used in lieu of the main supporting rod 11 should the latter become broken or otherwise impaired from constant use. Should the rod 11 become broken the latter is removed through the open tops of the hangers 5 and the auxiliary rod 28 interposed between said hangers at the side attaching ears 6 and secured to the support 8 by the screws 27 and in which position the seat 1 1 may be pivotally connected therewith by passing the hooks 16 over the auxiliary rod, as'will be readily understood.

The bottom of each hanger is preferably formed with an opening 29 and the heads 13 of the supporting rod are provided with .similaropenings 30 so as to permit the inser tion of bolts for the purpose of holding down the seat supporting rod, if desired.

While the seat is particularly adapted for use in the cabs of locomotives and the like for convenience of the engineer or fireman, it will of course be understood that said seat may be employed with equally good results for any other purpose without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is:

1. The combination with a support, of hangers secured to the support, cushioning members carried by the hangers, a supporting rod resting on the cushioning members, a seat pivotally mounted on the supporting rod and spacing members slidably mounted on the rod for centering the seat between said hangers.
